Abstract
The utility model relates to a titanium plate thin-walled volute plate structure. The titanium plate thin-walled volute plate structure is a concave surface plate; the peripheral edge of the titanium plate thin-walled volute plate structure is in the form of circular arc transition; the radius of a circular arc on one side is larger than that of a circular arc on the other side; a rectangular straight edge protruding outwards is arranged on one side with the smaller-radius circular arc; a convex rib is arranged towards the interior of the concave surface plate along the rectangular straight edge; the length of the convex rib is larger than half of the total length of the concave surface plate but smaller than the total length of the concave surface plate. The utility model provides the titanium plate thin-walled volute plate structure; the strength of the plate can be enhanced while the thin-walled volute plate is guaranteed as much as possible; the bending resistance of the titanium plate thin-walled volute plate structure is further enhanced by using the convex rib while the impact strength is enhanced; and the titanium plate thin-walled volute plate structure provided by the utility model has the advantages of reasonable structure, easy manufacturing and machining, high strength and good performance and is very beneficial for promotion and implementation.
Description
Technical field
The utility model relates to the spiral case parts of metal production industry, is specifically related to a kind of titanium plate thin-walled spiral case plate structure.
Background technique
Usually, the spiral case plate that be used for to form spiral case is that thin walled structures but intensity can not reduce, and existing spiral case plate can be easily impaired serious because of insufficient strength or unreasonable structure, affects the spiral case life-span.
Summary of the invention
The utility model provides the titanium plate thin-walled spiral case plate structure of a kind of internal diameter φ 20000 * 30 for situation about existing in the prior art and problem.
Technological scheme: a kind of titanium plate thin-walled spiral case plate structure, be a concave surface sheet material, the periphery arc transition, wherein one side radius of arc is greater than another side, be provided with outwards outstanding rectangle straight flange on one side of small radii circular arc, be provided with convex tendon along rectangle straight flange item concave surface sheet material inside, the length of this convex tendon greater than concave surface sheet material total length half but less than total length.
The outstanding curved portion of described convex tendon is positioned at the one side of concave face plate depression.
Inside width dwindles described convex tendon gradually from the ingress.
Beneficial effect: the utility model provides a kind of titanium plate thin-walled spiral case plate structure, when assurance spiral case plate is tried one's best thin-walled, can improve the intensity of sheet material, and concave face plate just when improving impact strength, utilizes convex tendon further to improve its bend resistance ability; It is rational in infrastructure, easily makes processing, and intensity is high, and performance is good, is beneficial to very much promotion and implementation.
Description of drawings
Figure l is the structural representation of the utility model titanium plate thin-walled spiral case plate structure.
Among the figure, label 1 is concave surface sheet material, and 2 is the rectangle straight flange, and 3 is convex tendon.
Embodiment
Embodiment one: referring to Fig. 1, a kind of titanium plate thin-walled spiral case plate structure, be a concave surface sheet material 1, the periphery arc transition, wherein one side radius of arc is greater than another side, be provided with outwards outstanding rectangle straight flange 2 on one side of small radii circular arc, be provided with convex tendon 3 along rectangle straight flange item concave surface sheet material inside, described convex tendon 3 outstanding curved portions are positioned at the one side of concave face plate depression.The length of this convex tendon 3 greater than concave surface sheet material total length half but less than total length.Inside width dwindles described convex tendon 3 gradually from the ingress.
